Something beyond the veil brushed your thoughts — a parasitic will, a whispering void, or the echo of an alien intellect. Now your mind exerts a gravity of its own, bending others through sheer presence and warping the brave into the broken.

Informational diagram: How sensory information is processed by the brain

Sensory information is taken in by the occipital lobe, parietal lobe, temporal lobe, and/or the olfactory lobe.

The lobes send the sensory information to the somatosensory cortex.

The somatosensory cortex sends the information to the thalamus, which connects to the limbic system.

The information is sent to the amygdala, which gives initial/primal reactions to the stimuli.

The amygdala's reactions (including fight or flight response) are sent to the hippocampus, hypothalamus, and the frontal cortex.

The pituitary gland receives signals from the hypothalamus, then sends signals for the endocrine system to excrete hormones throughout the body. The frontal cortex sends rationalized information to the motor cortex, which controls voluntary actions.

The Shape of Experience and the Hyperbolic Geometry in the Brain's Spatial Maps - Geometry Matters

Tatyana O. Sharpee’s work in the realm of geometric cognition—a field dedicated to understanding how the brain interprets and represents spatial information—has yielded groundbreaking insights into how our minds map the world around us. Continuing her previous argument for hyperbolic geometry in neural circuits, the recent paper, co-authored with Huanqiu Zhang, P. Dylan Rich, and Albert K. Lee, sheds light on the hyperbolic geometry of hippocampal spatial representations.

The hippocampus, a crucial part of the brain involved in memory and spatial navigation, houses ‘place cells’—neurons that fire when an animal is in a particular location. The geometry of these spatial representations, however, has remained largely unknown. Breaking new ground, Sharpee and her team reveal that the hippocampus does not represent space according to a linear geometry, as might be expected. Instead, they discovered a hyperbolic representation.

We investigated whether hyperbolic geometry underlies neural networks by analyzing the responses of sets of neurons from the dorsal CA1 region of the hippocampus. This region is considered essential for spatial representation and trajectory planning.

Imagine holding a map of your city. A linear representation would be akin to the map’s scale, where an inch on paper corresponds to a fixed number of miles in reality. A hyperbolic representation, in contrast, changes the scale depending on where you are on the map. The implications of this discovery are profound. A hyperbolic representation provides more positional information than a linear one, potentially aiding in complex navigation tasks.

This hyperbolic representation isn’t static—it dynamically expands with experience. As an animal spends more time exploring its environment, the spatial representations in its brain expand. The expansion is proportional to the logarithm of time spent exploring, suggesting our brains continually refine our spatial maps based on our experiences. As we spend more time in an area, our mental map of that area becomes more detailed and expansive. This dynamic updating could be crucial for efficiently navigating familiar environments.
